I got the following result, but I don;t know why it cannot draw the point on the gnuplot and the results in rx file are all zero.

Never work with GNU plot but you have defined it differently: rx_stream.dataFmt (12bit) and buffer (rx_buffer as 32bit float). TX definition is identical.

But the point in TX has phase shift, and points in RX are still around zero. (Problem nan has been solved.)
